Hi I wanted to learn using MPI in C. I am using Codeblocks on Windows 7
I ran this program:
#include <stdio.h>
#include <mpi.h>
void main (int argc, char *argv[]) {
int err;
err = MPI_Init(&argc, &argv);
printf("Hello world!\n");
err = MPI_Finalize();
}
but for some reason, i get an error at "mpi.h". Is there a way to add the library?

First, install an implementation of MPI. In the past I've used MPICH, but there are other implementations available. I know another is LAM/MPI. Check out the Wikipedia page for additional information at:
http://en.wikipedia.org/wiki/Message_Passing_Interface#Implementations
After you install MPI, use the sample code provided in the Wikipedia article to get comfortable.
Good luck!
